The High Occupancy Vehicle Lane Exemption Reauthorization Act is designed to extend the period during which certain alternative fuel and clean vehicles are permitted to use high-occupancy vehicle (HOV) facilities . This legislative action directly modifies Section 166(b)(5)(A) of title 23, United States Code, which governs these specific exemptions. The primary provision of the bill changes the existing expiration date for this authorization. Instead of expiring on September 30, 2025, the exemption will now be valid until September 30, 2026 , thereby granting an additional year of access to HOV lanes for qualifying vehicles.
